A land and boundary dispute between Santo Domingo Petapa and San Juan Mazatlán in Oaxaca turned deadly when a vehicle carrying members of the Unión de Comunidades Indígenas de la Zona Norte del Istmo, or Ucizoni, was ambushed near Río del Sol. According to the packet from Revista Proceso, three people were killed and a local official was reported missing after the attack.

The report says the incident happened around 2:30 p.m. on Thursday, February 13, in the area belonging to Santo Domingo Petapa. Ucizoni identified the dead as its delegate Wilfrido Atanacio and members Victoriano Quirino and Abraham Chirino. The organization’s leader, Carlos Beas Torres, confirmed the attack in the report, which makes the packet an account from inside the affected community rather than an official state briefing.

The violence appears linked to a wider conflict over municipal limits. Proceso says the ambush took place in the context of a border dispute between the two municipalities, and that people in El Platanillo were barricaded amid fears of further attacks from armed residents of Santo Domingo Petapa. That detail shows the incident was not only an isolated assault on a vehicle; it was part of a broader local confrontation with community-level fallout.

Ucizoni used the moment to demand action from the state government of Salomón Jara Cruz, asking it to act impartially and guarantee the population’s safety. The group also called on Oaxaca’s attorney general to act according to law and punish those responsible for the violence. Those demands matter because they show the organization does not view the event as a simple criminal case. It sees it as a test of whether authorities can manage a territorial conflict without taking sides.

The report also says Leonel Cristóbal, the municipal agent of El Platanillo, was missing after the ambush. That raises the seriousness of the situation even further, because the attack may have produced not only deaths but also an unresolved disappearance. In a region already tense from boundary disputes, a missing local official can deepen fear and make retaliation or further flight more likely.

The supplied report does not include a government account, a police casualty breakdown or a clear statement about who carried out the ambush. That absence is part of the story: the community says it was attacked, the state has not yet set out a full version, and the risk of further violence remains.

What is certain is that a dispute over land and local authority has crossed into fatal violence. Three members of Ucizoni are dead, one municipal agent is missing and the communities around Santo Domingo Petapa and San Juan Mazatlán now face the kind of uncertainty that can turn a boundary argument into a wider security crisis.
